CORPORATION OF CONNECTICUT.

MULTIPLE-PLUNGER MACHINE.

Application filed May 20,

T 0 all whom it may concern Be it known that I, ZENAS P. CANDEE, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain newand useful'Improvements in Multiple- Plunger Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

invention relates to a new and improved multiple plunger machine wherein a plurality of plungers, or gates carrying punches or similar tools, are used in conjunction with corresponding dies or tools suitably held. a

It is the object of this invention, among other things, to operate the several plungers or gates from a single crank shaft; to so construct the ways for the plungers or gates that they may be completely machined and assembled outside of the body of the machine and then as a unit-assembled therewith, and thereafter each of the ways for the separate plungers be independently removed and adjustable as well as the plungers themselves; and further to provide means whereby the relative endwise position of the plungers may be independently varied and separately adjusted.

' To these, and other ends, my invention consists in the multiple plunger machine having certain details of construction and combinations of parts as will be hereinafter described and more particularly pointed out in the claims. 7

Referring to the drawings in which like numerals of reference designate like parts in the several figures.

Figure 1 is an elevation of my new and improved mechanism shown assembled with such portion of the body of the machine and adjacent parts as are essential to a disclosure of its construction and operation.

I Figure 2 is an enlarged sectional view thereof taken substantially upon line 22 of Figure 1. I

Figure 3 is a sectionalplan view of a portion thereof taken upon line 33 of Figure 2.

Figure 4 is a detailed view of one of the sections of the eccentric sleeve.

Figure 5 is a fragmentary plan view of the way'frame and adjacent parts,

thereof, and Figure 7 is an enlarged elevation of the eccentric sleeve.

Heretofore it has been the general practice to operate the several plungers or gates of a multiple plunger machine by means of cams, toggles or similar mechanism.

In my new and improved machine I am able to operate a plurality of independent plungers or gates from a single crank shaft, each of these plungers being independent of each other, operated in independent ways and separably removable and adjustable.

The form or shape of the body of the machine to which my invention is applied is not material, but I have shown in'the drawings one of such forms wherein the numeral 10 designate the machine, which is of the press type, having parallel portions connected at one end by a bed 11 and at the other end by a head portion 12 and within which is journaled a crank shaft13. This crank shaft is shown as having three cranks 4L2, but a greater or less number may be used as desired and on each side of each of the cranks are cheek portions 14;. The two intermediate cheek portions are journaled in the bearings 15, providing a support for the crank shaft between its main journals in the machine 10.

The means for pivotally connecting each of the plungers or gates 16 with the crank of the crank shaft 13 comprises the connection 17, cap 18 secured thereto by screws 19 or similar means, eccentric bushing 20, swivel block 39 hinged to the plunger 16 on the swivel pin 40 and secured to the connection 17 by the key 41. By removal of this key ll the plunger 16 and the swivel block 39 therewith are separated from the connection 17. The bushing 20 is constructed of two sec tions, the side elevation of one of 'which is shown in Figure a, having an opening 21 therethrough of the same diameter as the cranks 42, with its outer surface 22 eccentric therewith, and provided with a flange 23 at one end. For convenience in machining and assembly a tongue and groove joint 24 is provided to insure a proper alignment of each of the sections in relation to the other. In the periphery of the flange 23 are a plurality of holes 25 into which a rod (not shown) is inserted for the puropse of rotatof the crank 42.

The outside diameter of the bushing 20 is the same as the bore in the connection 17 and cap 18 and when inserted therein, as shown, is held against relative movement by the frictional engagement of these parts there with.

In assembling the bushings 20 are placed on the shaft as shown in Figure 1, the outer faces of the flanges 23 preferably in contact with or adjacent to each other and their opposite ends adjacent to the cheeks let of the crank shaft. After the bushings are located, the connections 17 are placed in position and the caps 18 secured thereto, at whioh time the bushings, connections and capsa-ll form one unitary structure.

T e y the re ative posi ion o the n nneetiene ncljthe cranks, the e eentri bush g 20 .ie n ed sheet t e there and When thezd ei eclipeei ien r eohtained th Pa ts are hen aga eeenredtegether lnipuletien f t e nuts .19 en lthe ee ne tien oper es n it ne r lative po tion- .Thi ju tment P ovid for a lim te r ation in h P s tion f t e gate 16- I am able by the means above described to operate the several gates from a crankshaft, the mechanism for connecting the same be ing comparatively simple and readily assembled and each gate is operated independently of every other gate. Its relative position in relation to the crank may be varied atwill without regard to any other gate and the s f tse f tateh' y enppe and moun d 1 as to thstand e, greatest preeen e put upon it l'eng'h theepere-t en ef the m le :i he ga e Secured withinthe machine 10 by screws 26, or other suitable means is a way frame 27 provided with a plurality of recesses 28 corresponding in number with the plungers 16 and secured to the sides 2-9 of this way frame near the top and bottom thereof, by bolts 30, or similar means, are the plates .31 having recesses 32 therein which .are opposite to the recesses 28 and within which are connected the ways 33 between which the gates 16 are movably mounted.

The ways associated with the, way me 27 a e e d t ereto by th s re 6 and the ways 3. a eee et d-with the plate 3 are adjus abjly s cur hele nll y th belts and helclin hei dj ste pesit ene by the sc ew 36- o va y th i andeutpee' tien of th were just re rr d o, th eerewe 3 a e .loee n d and th brought to i s new position through manipulation of the screws 35 and is there held with the ends of the screws 36 impinging against the face of the ways. By this means of holding .the ways, their position may be varied to take up wear and by releasing the screws 35 therefrom without disturbing the screws 36, h y can he removed nd retu ned t their former position without further adjustment,

rota y element; pl

outside of the machine 10. This will very much reduce the, cost of construction and facilitate the assembly of the parts with ex n ss and nine y befo eingp eed in t machine itself- Again if it is des red a e ake ou any o e of th eysit .ie n y neeee e y t release the screws 3 therefrom and hen allow the to drop out, or if the space be ow thejlew r pla e s ,noteufiieient to p mi his, thel-ette he -.liem.ev rl, and the ay d epp 'l a eu e ent d stenee t a l w the op thereof o pas nncler'the upper pl t .1, or i he rase s SO en reeted' o o admit h endw semo elnent hot-h pla eefil m y he rem ved an the Way aken out without endwise movement.
